Aims: We pose the question of how much information on the atmospheric parameters of late-type stars can be retrieved purely from color information using...
Learning to do multiframe wavefront sensing unsupervised: Applications to blind deconvolution
Context. Observations from ground-based telescopes are severely perturbed by the presence of the Earth's atmosphere. The use of adaptive optics techniques has...
LeMMINGs. V. Nuclear activity and bulge properties: A detailed multi-component decomposition of e-MERLIN Palomar galaxies with HST
We used high-resolution HST imaging and e-MERLIN 1.5-GHz observations of galaxy cores from the LeMMINGs survey to investigate the relation between optical...
Lens parameters for Gaia18cbf - a long gravitational microlensing event in the Galactic plane
Context. The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive...
Li abundances in F stars: planets, rotation, and Galactic evolution
Aims: We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective...
Li depletion in solar analogues with exoplanets. Extending the sample
Aims: We want to study the effects of the formation of planets and planetary systems on the atmospheric Li abundance of planet host stars. Methods: In this work...
Limited impact of jet-induced feedback in the multi-phase nuclear interstellar medium of 4C12.50
Context. 4C12.50 (IRAS 13451+1232) at z = 0.122 is an ultraluminous infared radio galaxy that has often been proposed as a prime candidate for the link between...
Limits on the orbits and masses of moons around currently-known transiting exoplanets
Aims: Current and upcoming space missions may be able to detect moons of transiting extra-solar planets. In this context it is important to understand if...
We report on H-band, ground-based observations of a transit of the hot Neptune GJ 436b. Once combined to achieve sampling equivalent to archived observations...
